At the end of this report we draw up the balance of our work having led to the implementation of a mail solution with online storage in SSO portal. The first step was the collection of information that allowed us to make a complete study on the project. We then studied the single sign-on and mail solution. This allowed us to identify its different components and the way they are designed and interact with each other. Then, we studied in more detail the deployment steps of this solution. In this book, we encountered some difficulties such as the problem of interaction between sso and owncloud. This fruitful experience allowed us to acquire new knowledge in the field of virtualization and more particularly by the technical mastery of the virtualization products proposed by Vmware (Vsphere ) and the field of cloud and Linux systems configuration.
